Interview.

I landed an interview next week at a cardiothoracic unit (tele / step down unit / med surg / surgery). Anyone have tips? What questions to expect, etc.. etc.. Attire for males?

There are many threads on this topic that you might find of assistance...such as this one:

It seems the newest style of interviewing especially in healthcare is the behavioral interview. There are also lots of threads on proper interview attire.

Good Luck!
